Abstract
FH signal in Satellite TT&C link yields divergence when traveling through ionosphere, which brings about “Chip Scintillations” of PN code chips at the transition of two adjacent frequency hops in DS-FH signal. Signal model of DS-FH TT&C link in IONOSPHERE is established for further study and deterioration in PN code tracking of DLL caused by chip scintillations is investigated. Simulation results for different application scenarios are valuable for the design of Secure TT&C system of satellite.
